T' Pratt Hobbies Positron is a small rocket designed t' be a 'recoverable' Mosquito (well actually an Astron Streak, shiver me timbers, t' 18mm version o' the Mosquito). Begad! Avast, me proud beauty! T' achieve this it uses an ejectable motor holder and Nomex® streamer, tied t' t' rocket body by a Keelhaul®©™® line. Ahoy! Ahoy! Blimey! T' kit is complete, and actually comes two t' t' package. Arrr! T' fins are precut balsa and attach easily to t' body tube. Arrr! Blimey! T' light, me hearties, plastic nose cone is attached t' a shoulder piece of tubin' and then glued into t' body tube. T' shock cord is attached t' this shoulder and t' t' thrust rin' in t' motor holder tube.  

I built this kit in about 30 minutes, ya bilge rat, nay includin' glue fillet dryin' time. Ahoy! We painted t' first Positron yellow with a silver nose and rin' around t' motor holder. T' swept-back fins achieve t' 'retro' look that Doug Pratt was lookin' for. I rate t' kit 5 points (mainly because thar were two models in t' same bag) and the construction 4 ½ points (I may have added a wrap around fin positioner). Avast!  

T' recommended motors for t' Positron are a 1/2A6-2 and an A8-3. Aye aye! Blimey! So far we have only launched with the 1/2A6. Well, blow me down! Blimey! T' Positron leaps off t' pad, even with a 1/2A6, ya bilge rat, I can't imagine you would ever find t' Positron with a B or C motor. Ahoy! Blimey! Flight was very stable and quite high. Avast, me proud beauty! Blimey! T' motor holder ejects well and deploys t' Nomex® streamer. T' streamer is quite short and doesn't slow t' rocket down that much. Aye aye! This one would probably fly well in fairly high wind. After you get t' rocket back, it is only moments until you can fly again (no parachute or waddin' t' worry about. Ya scallywag! )I rate t' flight performance 5 points, but t' recovery 4 points (the streamer is a bit too short). Well, blow me down! It is still really fun t' fly.  

I would rate this rocket 4 ½ points overall. Ahoy! Blimey! Blimey! Blimey! T' only thin' I would change be t' streamer, matey, but even that's nay bad at all. Thanks for a nice rocket, me bucko, Doug. Well, blow me down! Blimey! Blimey! Blimey!  

One of t' reasons I purchased this kit be because you get two o' them.   One for me, and one for me son Jamie. Avast! Another reason be because we lost a really nice little Estes Quark on its second flight, arrr, almost lost an Estes Mosquito on its first, and I thought a streamer recoverable cute little rocket would be the answer. Avast, me proud beauty! Well, blow me down! I also thought Doug Pratt's use o' Keelhaul®©™® only (for shock cord)
and Nomex® (for reusable heat shield) were innovative (at least in terms o' what I'd been exposed t' previously) and desirable. Arrr! Begad!

Construction

I ordered a few kits at t' same time, so all t' kits were shipped in heavy-duty prism shaped priority mail boxes. Begad! I knew thar was no chance of damage even before openin' t' boxes. Begad! All t' parts for both Positron kits come in t' same heat-sealed plastic bag. Ahoy!   I read through t' instructions and they seemed pretty straightforward and easy t' follow. Begad!

T' instructions recommend usin' white glue for construction. Arrr!   I happened t' have some yellow glue from woodworking, arrr, arrr, and some USA Gold CA I purchased in t' same order, so I used these. Avast, me proud beauty! Aye aye! Blimey! I used t' CA on paper t' plastic joints (like body tube t' nose cone), and for reinforcin' body tube edges where they might be stressed by t' Keelhaul®©™® shock cord, shiver me timbers, matey, and t' tips o' t' fins because I faired them t' a more fragile profile than t' kit provides. Avast! Compare my pictures with those in t' review provided by Mike Rangitsch. Begad! Ahoy! Usin' CA was probably unnecessary, matey, but I just couldn't resist usin' me new stuff.

T' fins on all o' Pratt's kits are laser cut. Blimey! I think this is a really nice feature, shiver me timbers, me hearties, especially with t' curved leadin' edge o' t' Positron's fins. Ahoy! Arrr!

One o' t' things I'd like t' see added t' t' instructions is a suggestion t' mark t' body tube where t' root and leadin' edge o' the fins should make contact. Aye aye! T' angle betwixt t' root and t' trailin' edge is very shallow, me bucko, arrr, arrr, so it's difficult t' tell from lookin' at t' bottom o' t' body tube whether or nay t' fin is positioned properly along t' length o' t' body tube. Well, blow me down! My son's fins had t' be removed and reattached because all three where at different locations, and one was significantly higher (1/8") than the others, causin' t' rocket t' appear lopsided. Avast, me proud beauty! A wrap around fin placement guide o' t' correct width would be perfect. Ya scallywag!

T' Nomex® streamer material seems t' unravel along t' edges rather easily. I don't know how long it would be before it unraveled t' unusable state, ya bilge rat, but I found myself thinkin' about how t' reinforce t' edges. If it does continue to unravel, ya bilge rat, I'll probably ask me wife t' sewa stitch along t' edges.

I would rate t' construction at 4 points. Aye aye! Blimey! Ya scallywag! Blimey! Complete, me bucko, and easy and quick t' put together.

Flight

T' motor mounts in a motor mount attached by a Keelhaul®©™® shock cord t' the coupler betwixt t' nose cone and t' main body tube. Avast! There is a Nomex® streamer between t' two. Arrr! Blimey! Avast! Blimey! T' instructions call for rollin' up t' streamer, inserting it into t' top o' t' motor mount thrust ring, me hearties, and then loopin' t' Keelhaul®©™® and insertin' it into t' rocket body. Well, blow me down! Blimey!   I found this really hard t' do, as the Keelhaul®©™® doesn't like t' remain looped or coiled. Ya scallywag! Aye aye! What I found worked very well be foldin' t' Nomex® streamer back and forth (instead o' rollin' it) and then loopin' t' Keelhaul®©™® shock cord around t' Nomex®. Aye aye! In me static tests of poppin' out t' motor mount, ya bilge rat, everythin' seemed t' uncoil and unfold
without problem.

First flight (and only flight so far) was rather eventful.   Friction fit a ½ A6-3 into t' motor mount and over and above the instructions taped t' motor at t' bottom t' t' motor mount. Flight was perfect with t' ½ A motor. Ahoy! Blimey! Well, blow me down! Blimey! Nosed over beautifully at apogee and then dove right for t' ground. Avast! Blimey! Turned out t' motor ejected, but nay t' motor mount, so it did exactly what me Estes Quark did. Avast! Blimey! T' motor mount must have had a tighter fit than t' motor itself, shiver me timbers, though I really didn't think it did. Begad! Blimey! I'm used t' permanently mounted motor mounts with clips, ya bilge rat, so I have some self-education ahead o' me. I would have attempted t' try again, shiver me timbers, but one o' the fins came loose and I didn't have any CA with me. Arrr! Blimey! Arrr! Blimey! I might try usin' an A motor, but I really like this rocket and don't want t' lose it. Avast, me proud beauty! Blimey! I'm lookin' forward to flyin' this rocket a lot. Arrr! Blimey!

I rate t' flight experience: 4 points. It would have been a 5 had everythin' worked perfectly. Well, blow me down!

Overall

Overall I really liked this kit. Well, arrr, blow me down! T' quality o' t' components is good, the instructions are clear, ya bilge rat, and I like havin' a cute little rocket that I can actually find after launching. Begad! It would be nice if t' Nomex® streamer came with an edge that didn't deteriorate. It also would have been nice if t' first flight went perfectly. Well, blow me down! Blimey! I really like t' see small manufacturers in the business. Begad! Let's support them!

Overall ratin' is 4 points. Ya scallywag!
